"Vapor Pressure of Water" assignment:
VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...

A student leaving campus for spring break wants to make sure the air in her dorm room has a high water vapor pressure so that her plants are comfortable. The dorm room measures 3.38 m x 4.61 m x 3.47 m and the student places a pan containing 1.59 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when she closes the door, and that the temperature remains...

I have to obtain the water vapor pressure and the partial pressure of butane from two trials of a Gas Laws experiment. I have my answers, but I am not very confident in my process and answer. Trial 1: Temperature of Water and Lab: 18.3 c Mass of Butane released: .028g Volume of Butane: 16.0g Barometric Pressure: 626.6 mm Hg Trial 2: Temperature of Water and Lab: 18.3 c Mass of Butane released: .013g Volume of Butane: 15.1g Barometric Pressure:...

1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...
